Definitions

  • the present invention is directed to a hand-held epilating device, more particularly to such a device having a plucking cylinder which is driven to rotate for plucking body hairs.
  • U.S. Patent No. 5,857,903 discloses a hand-held epilating device according to the preamble of claim 1 having a rotary cylinder which is provided with sets of pinching elements for pinching body hairs therebetween.
  • the rotary cylinder is driven to rotate about its longitudinal axis to pluck the pinched hairs.
  • the rotary cylinder is supported to a head member fixed to a housing grasped by the hand of a user so that the pinching elements on the rotary cylinder traces only a circular path around the rotary cylinder and do not move in the other directions relative to a skin surface of the user when the rotary cylinder is held against a fixed area of the skin surface.
  • the hairs at the portions corresponding to gaps between the adjacent sets of the pinching elements have no chances of being plucked. That is, the hair plucking is made to limited portions within the area of the skin covered by the rotary cylinder, posing insufficient plucking efficiency.
  • WO-A-0101812 establishes prior art according to Article 54(3) and (4) EPC and shows a hand-held epilating device according to claim 1 with the exception that the plucking cylinder does not reciprocate relative to the housing along its longitudinal axis.

  • the plucking cylinder has a longitudinal axis and is driven to rotate about the longitudinal axis to pluck the body hairs from the user's skin.
  • the plucking cylinder is supported to the housing so as to effect a periodical movement relative to the housing within a plane parallel to the longitudinal axis.
  • the area of the skin covered by the plucking cylinder can have increased chances of being in contact with the pinching elements as the pinching elements move periodically relative to the skin together with the plucking cylinder, thereby improving the plucking efficiency.
  • the plucking cylinder is arranged to reciprocate relative to the housing along the longitudinal axis so that the pinching elements on the plucking cylinder move along the longitudinal axis to cover a wide area of the skin along the length of the plucking cylinder.
  • the plucking cylinder reciprocates relative to the housing between two end positions and is held temporarily at each of the end positions for a short time interval during which the plucking cylinder rotates to such an extent of completing one epilating action of catching the body hairs between the pinching elements and plucking the body hairs.
  • the hair plucking is made both at the two axially spaced end positions with the same set of the pinching elements.
  • the plucking cylinder has a neutral position between the two end positions and is held temporarily at the neutral position for a short time during which the plucking cylinder rotates about the longitudinal axis to such an extent of completing one epilating action of catching the body hairs between the pinching elements and plucking the body hairs.

  • the head frame is movably supported to the housing and is coupled to the plucking cylinder so that the head frame makes the periodical movement together with the plucking cylinder.
  • the head frame may be fixed to the housing so that the plucking cylinder makes the periodical movement relative to the head frame.

Therefore, the hair plucking can be made at three different positions, while it is possible to minimize a transition period for movement between the neutral position to the end positions for further enhancing the plucking efficiency.

  11. Handgerät zum Enthaaren nach Anspruch 1, dadurch gekennzeichnet, dass das Gehäuse mit einer Kopfabdeckung (38) versehen ist, die eine obere Öffnung aufweist, durch die die Klemmelemente zum Erfassen der Körperhaare freiliegen, wobei die Kopfabdeckung an dem Gehäuse beweglich gehalten wird und mit dem Zupfzylinder so gekoppelt ist, dass die Kopfabdeckung die periodische Bewegung gemeinsam mit dem Zupfzylinder durchführt.
  12. Handgerät zum Enthaaren nach Anspruch 1, dadurch gekennzeichnet, dass sich der Zupfzylinder (60A) entlang einer Richtung hin- und herbewegt, die senkrecht zur Längsachse sowie zu einer aufrechten Achse des Gehäuses (10A) verläuft.
  13. Handgerät zum Enthaaren nach Anspruch 12, dadurch gekennzeichnet, dass die Klemmelemente (71 A, 72A) entlang der Längsachse des Zupfzylinders angeordnet sind und eine Länge entlang eines Umfangs des Zupfzylinders aufweisen, wobei sich der Zupfzylinder mit einer Amplitude hin- und herbewegt, die im wesentlichen gleich der Länge des Klemmelements ist.
  14. Handgerät zum Enthaaren nach Anspruch 12, dadurch gekennzeichnet, dass sich der Zupfzylinder (60A) zwischen gegenüberliegenden Endpositionen hin- und herbewegt und an jeder der gegenüberliegenden Endpositionen für ein kurzes Zeitintervall temporär gehalten wird, während dessen sich der Zupfzylinder in einem Maße dreht, dass ein Enthaarungsvorgang aus Erfassen der Körperhaare zwischen den Klemmelementen und Zupfen der Körperhaare ausgeführt wird.
  15. Handgerät zum Enthaaren nach Anspruch 14, dadurch gekennzeichnet, dass der Zupfzylinder (60A) eine neutrale Position zwischen den gegenüberliegenden Endpositionen aufweist, und an der neutralen Position für eine kurzes Zeitintervall temporär angehalten wird, während dessen sich der Zupfzylinder in einem Maße dreht, dass ein Enthaarungsvorgang aus Erfassen der Körperhaare zwischen den Klemmelementen und Zupfen der Körperhaare ausgeführt wird, wobei sich der Zupfzylinder zwischen der neutralen Position und den Endpositionen mit einer Geschwindigkeit bewegt, die größer als die Umfangsgeschwindigkeit des Zupfzylinders ist.
  16. Handgerät zum Enthaaren nach Anspruch 12, dadurch gekennzeichnet, dass sich der Zupfzylinder (60A) mit einem Hin- und Herbewegungszyklus hin- und herbewegt, der größer als ein Drehzyklus ist, mit dem der Zupfzylinder eine Drehung um die Längsachse ausführt.
  17. Handgerät zum Enthaaren nach Anspruch 16, dadurch gekennzeichnet, dass der Hin- und Herbewegungszyklus das Doppelte des Drehzyklus beträgt.
  18. Handgerät zum Enthaaren nach Anspruch 1, dadurch gekennzeichnet, dass sich der Zupfzylinder (60) entlang der Längsachse sowie entlang einer Richtung senkrecht zur Längsachse hin- und herbewegt, um eine Translationsbewegung relativ zum Gehäuse zu bewirken.
  19. Handgerät zum Enthaaren nach Anspruch 1, dadurch gekennzeichnet, dass der Zupfzylinder (60; 60A) mehrere Sätze von Klemmelementen (71, 72; 71A, 72A) trägt, die um die Längsachse umlaufend beabstandet sind, wobei jeder Satz von Klemmelementen ein bewegliches Element (72; 72A) enthält, das angetrieben wird, um sich entlang der Längsachse zum Zupfen der Körperhaare zwischen den Klemmelementen zu bewegen,
    der Zupfzylinder eine Vielzahl von Steuerwellen (82, 83) trägt, die sich parallel zur Längsachse erstrecken und um die Längsachse umlaufend angeordnet sind, wobei jede Stellwelle ein erstes Ende, das mit dem beweglichen Element zum Antreiben des beweglichen Elements (72) in Eingriff steht, und ein zweites Ende aufweist, das auf einer Stirnseite des Zupfzylinders für einen Eingriff mit einem an der gegenüberliegenden Stirnseite angeordneten Nocken (50) vorsteht,
    wobei der Nocken für einen selektiven Kontakt mit den zweiten Enden der Stellwellen derart positioniert ist, dass die Stellwellen in einer Richtung des Klemmens der Körperhaare zwischen den Klemmelementen bewegt werden, wenn sich der Zupfzylinder um die Längsachse dreht,
    wobei das zweite Ende jeder Stellwelle so gestaltet ist, dass es sich um die Längsachse auf der Stirnseite des Zupfzylinders umlaufend erstreckt, um einen bogenförmigen Flansch (84, 85) zu ergeben,
    wobei die bogenförmigen Flansche der umlaufend benachbarten Stellwellen in einer radialen Richtung teilweise miteinander überlappen, so dass die überlappten Abschnitte der bogenförmigen Flansche mit dem Nocken simultan in Kontakt geraten.
